For ATO-compliant GST: Saasu = yes, SumUp Invoicing = limited. For native ABN field: Saasu = yes, SumUp Invoicing = limited. If you operate in Australia and either tool falls short here, InvoiceSonic handles both natively — and it's free.
Most freelancers want fast invoicing without paying for full accounting. Between these two, Saasu wins more categories overall. But if you're a freelancer who just wants ATO-compliant tax invoices for free, InvoiceSonic is purpose-built for that workflow.
Do not assume a one-click migration. Confirm each product's current export and import formats, then test contacts, opening balances, unpaid invoices, tax codes, attachments and reconciliations before cancelling the old account. Keep statutory records outside both systems.
Both tools include more than invoicing. If invoicing is your only need, a dedicated generator can be faster and more focused than a full accounting subscription.
Yes — InvoiceSonic lets you create and download an invoice without signup. Its account plans have separate limits and pricing, so compare current official plans before deciding.
